Represents a message that is received from the event bus in a handler.
 Messages have a body, which can be null, and also headers, which can be empty. 
 If the message was sent specifying a reply handler, it can be replied to using reply. 
 If you want to notify the sender that processing failed, then fail can be called. 
 NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen. /**
